While this one will most likely miss us, not by much in cosmic terms, it should awaken us more to the fact that such a hit can occur. While the odds of us being hit by any given asteroid, comet or meteor is small, we do get hit. Luckily, not by a large one in quite awhile. But, given a long enough time period and our odds will eventually fall to zero and we will get hit by a large object moving pretty fast. The real question is not if, but when and will we be prepared for it? Will we have allocated enough research and infrastructure to stop it or deal with it? Will we have a workable plan to save enough of humanity for the human species to survive? What this should make us realize is that the cosmos is shooting at us, although, not very accurately, it will someday hit us.
The planet Earth, aka Terra, aka Sol III, is too small and fragile of a basket for humanity to keep all it's eggs in any longer than it has to. In order to increase the odds of mankind surviving into the distant future, we must start moving enough people to maintain genetic viability and our technological status off of this one planet as soon as it is feasible.
Besides the threat of asteroids, comets and other cosmic debris hitting us, we still live under the threat of some not so conscientious individuals causing a nuclear winter. For those who thinks this cannot happen, we are smarter than that, then consider that Iran and other Jihadist leaning nations are seeking nuclear weapons.
Another threat that people are not commonly aware of is the Yellowstone Volcano. For those not familiar with it, most of Yellowstone National Park sits inside of a Super or Mega-Volcano. It has the largest magma chamber known to mankind, it is also the most studied volcano. The last Mega-Volcano to erupt was in Indonesia, approximately 70 thousand years ago. It is believed to have cause an Ice Age. Yellowstone is larger. Yellowstone is also approximately 20 thousand years past it's normal eruption cycle and the magma chamber is filling. It's eruption is not an if, it is also a when and at what magnitude. We know of this threat, will we be prepared when it comes or will mankind become extinct because it again refuses to take steps necessary to ensure it's own survival?
Here are ten more ways in which the world might end.
So, what do we do about it? We humans live in only one habitat, as far as we know anyway, and this little dust mote orbiting one star of hundreds of billions of other stars in one minor galaxy, one of hundreds of billions once again.
If we were to find a unique species living only on one small island, we'd call it an endangered species. Is humanity an endangered species? What does it matter?
Just how important are human beings anyway?
Can't we just turn Congress off and then turn it back on again?
